Eg 1.

data compound;

     Amount=50000;

     Rate1=.075;

     Yearly=Amount*Rate1;

     do i=1 to 12;

         Monthly+((Monthly+Amount)*(Rate1/12);

end;

run;

proc print data=compound; run;

output:

O  Amt     Rate1 Yrly    Mnthly

1500000.07537501261.77

Why isn't I = 13 in the  output?

Eg 2.

Here yearly does in fact show in the output and is incremented +1 _n_ ....

data invest;

     Capital=0;

     do Year=2001 to 2003;

             Capital=5000;

             Capital+(Capital*.075);

end;

run;

proc print data = invest; run;

Output:

O Cap   Yr

Because the typo in the first data step makes it not run.  So it didn't overwrite the previous version of the data set named COMPOUND.

1244           Monthly+((Monthly+Amount)*(Rate1/12);

                                                   -

                                                   79

ERROR 79-322: Expecting a ).

That is correct.

BTW you may want to investigate financial functions in the SAS help. They can save a lot of coding for common calculations.
